50.5 m
Explanation:
We are given that
Velocity=v=19.5m
Vertical component of initial velocity=![v_y=vsin\theta=19.5sin33.5=10.8m/s](/tpl/images/0522/4991/eb4be.png)
Height=h=-14.5 m
Acceleration due to gravity=![g=-9.8m/s^2](/tpl/images/0522/4991/fba6a.png)
By solving we get
Time cannot be negative
Therefore, time=3.1 s
Horizontal component of velocity=![v_x=19.5cos33.5=16.3m/s](/tpl/images/0522/4991/d45cc.png)
Distance=![x=v_xt=16.3\times 3.1=50.5 m](/tpl/images/0522/4991/b2a31.png)
Hence, the golf ball travel horizontally before it hits the water=50.5 m
